Decent, but the sequel is better.

Rating: 9/10 (19 June 2007)

I can't say that this one is exactly... a classic. It's based on a "Rage" virus that if caught, inevitably causes mass anger and reanimation of following death- much like the "T" Virus of "Resident Evil". It's basically just another zombie film.
However, it has some interesting twists. Instead of seeing the same old, same old, they twist it up a bit. The infected has involuntary muscle spasms, and will be running around like maniacs at the sight of "prey". There's no reasoning with these. There is no tying them up and teaching them meaning to life. Not here. And that's a slight beauty of it.
I can most certainly say, though, that it's sequel, "28 Weeks Later" is far, far better. There's much more action, much more drama, and a lot more horror. One of those movies that gives you companionship with a warm-hearted character that later has something happen to them that causes complete change. THAT'S scary, and that's what the "28 Days/Weeks Later" films have to offer.
